Elliptic Flow Fluctuations at NICA Energy Range

Abstract

One of the primary observables that is sensitive to the transport characteristics of the strongly interacting matter created in relativistic heavy-ion collisions is the elliptic flow \({{v}_{2}}\) of the produced particles. The relative elliptical flow fluctuations are of great interest because they can be used as a probe of the initial conditions using the ratio of cumulants \({{{{v}_{2}}\{ 4\} } \mathord{\left/ {\vphantom {{{{v}_{2}}\{ 4\} } {{{v}_{2}}\{ 2\} }}} \right. \kern-0em} {{{v}_{2}}\{ 2\} }}\). In this work, we study the centrality dependence of elliptic flow fluctuations using the state-of-the-art models of heavy-ion collisions spanning the range \(\sqrt {{{s}_{{NN}}}} \) = 5–11 GeV.
